摘要
Let us assume that (B-t((1)), B-t((2)), B-t((3)) + mu t) is a threedimensional Brownian motion with drift mu, starting at the origin. Then X-t = vertical bar vertical bar (B-t((1)), B-t((2)), B-t((3)) + mu t) vertical bar vertical bar, its distance from the starting point, is a diffusion with many applications. We investigate the supremum of (X-t), give an infinite- series formula for its distribution function and an exact estimate of the density of this distribution in terms of elementary functions.
